Question : 21

Total: 100

Comprehension:(Que No. 21 - 25)

Answer questions based on the following passage.
The great white shark is larger, faster and more dangerous than most sharks. It can reach a length of 20 feet and weigh 70,000 pounds. Though its preferred diet is seals and dolphins, this fearsome fish regularly attacks almost any type of warm-blooded animal. In its snout are small holes that lead to receptors. These receptors pick up electrical nerve signals in the prey. The shark also has other sensors that detect blood in the water. Very rare in tropical or polar regions, great whites patrol mainly in temperate ocean coastlines. Their body is designed for efficiency in the water. It is broad in the middle and tapered at the ends for streamlined movement. Wing-like pectoral fins provide lift and stability. Oil stored in the liver adds buoyancy. The tail fins are vertical and act as a rudder for fast turns. Amazingly, it never stops swimming. All sharks are fish and most are carnivores. The great white is the world's largest predatory shark. The whale shark is near twice as big, but like a Baleen whale, eats mainly plankton. The Blue Whale is the largest known mammal to ever live. Its size ranges from 70 to 100 feet in length and up to 125 tons (250,000 pounds) in weight.
